Hey everyone, now, I have another problem that I can't solve on my own....not like that one yesterday which was.... Okay, I use Debian 8 with the latest stable build of ISPConfig. I also implemented Let'sEncrypt which works fine. I also configured ISPConfig to answer on servername:443 instead of servername:8080 Problem is: Since a few hours (without changing anything) I get the above mentioned error.... well, Actually, I only get "\x16\x03\x01" in the "other_vhost_access.log" in /var/log/apache2/ And I have absolutely no Idea, why! Does anyone here have experience with this issue. It only happens when I directly access the server FQDN (in my case: asuna.example.com (domain name changed)), it doesn't happen when I directly access one of the vhosts via HTTPS (one site I host there is fully encrypted with a Thawte Cert). Thank you very much in advance. Regards Zero
